Application filed October 29, 1923. 1 Serial No. 571,313.,

7 To all to 7mm tmay concern a citizen of the United States, residing at Omaha,in the county'of Douglas and State of- Nebraska, have invented certain new and useful Improvementsi'n Carrier Mechanism, of which the following is 'a specifica-' tion. I

This invention relates to carrier mechanism, useful for moving loose earth, coal or other material, and particularly of advantage for filling ditches, and has for itsob:

ject to provide parts so constructed and arranged that large volumes of earth orother material maybe moved quicklyand con' veniently by a single operator, and that stressesincidentjto the use-of these parts will bev sustained to advantage, said parts to befewand simple in order that durability may be attained and manufacture will be economicah The invention is illustrated as a backfiller for ditches, and includes a motor ve-' hicle' adapted to be moved from time to time as the work progresses, said vehicle be- I ing provided with all of the mechanism .re-

quired, such as a boom orderrick adapted to be extended to overhang the ditch and earth .to be moved, a scraper or'shovel provided with cables and ail, arrangement of drums under control of the operator for moving the shovel. The invention also includes'means forhsupporting the derrick at selected deeesof inclination and discloses bear ngs iii certain shafts tending to materially re duce friction and arranged to be housed from the weather or other exposure. Other features considered to be new "and useful will be hereinafter'explained in detail.

It" will be appreciated that ,the operating shaft 9, on: .accountlqof. stresses directed thereto, should" be firmlyfsupport'ed; and

that its. bearings should begprotected from V thepresence offlloose earth'or dust, audit is be'lieved that the':eonstruction vas 'shown fandfd escribed provides these features.
